Back when Alias Enterprises(now called Lamp Post Inc.)did non-Christian comics, one of the titles they did a one-shot graphic novel called OZF5-Gale Force.
This alternate version of the original Wizard Of Oz opens up with Lion, Scarecrow, and Tin Woodman as might warriors fighting off the mechanical Winkie army of the Wicked Witch of the East(who's dressed like she's out of Aladdin!), and gets squashed by Dorothy's house. A modern-day Dorothy then emerges and helps them defeat the rest of the Winkies. The West Witch(who appears like she was modeled alot after Wicked)then sends her squadron of monkeys with jetpacks after them while Dorothy and the Oz warriors head to see the Wizard to send her back to Kansas. But, Dorothy confronts the Witch and defeats her. She's then declared the new Witch of the West by the monkeys.
This supposed to be the first of a series involving some "Witch Wars" in Oz, but currently only this one volume was made. The comic is available from regular dealers like Amazon. You can also now download it at Itunes.
